Excitation induced emission color change based on Eu(III)-Zn(II)-containing polymer complex.


A novel polymer P-1 is prepared by the reaction of the monomer 5,5'-divinyl-2,2'-bipyridine and Salen-Zn(II) via Heck cross coupling. Interestingly, P-1 can further incorporate with Eu(TTA)(3)·2H(2)O to generate copolymer P-2 with two different metal centers. P-2 exhibits exceptional dual emissive properties which can be tuned by excitation wavelength. For… (More)
